Arsenic (+3 Oxidation State) Methyltransferase (AS3MT) ELISA试剂盒

AS3MT catalyzes the transfer of a methyl group from S-adenosyl-L-methionine (AdoMet) to trivalent arsenical and may play a role in arsenic metabolism (Lin et al., 2002 [PubMed 11790780]).[supplied by OMIM, Mar 2008].. 再加上，我们可以发AS3MT 抗体 (23) 和 AS3MT 蛋白 (7)和数多这个蛋白质的别的产品。

combined effect of N6AMT1 haplotype 2_GGCCAT and As3MT haplotype 2_GCAC showed consistence with the additive significance of each haplotype on % iAs: the mean was 5.47% and 9.36% for carriers with both and null haplotypes, respectively

Maternal alleles for five of the seven SNPs (rs7085104, rs3740400, rs3740393, rs3740390, and rs1046778) were associated with urinary concentrations of iAs metabolites, and alleles for one SNP (rs3740393) were associated with birth outcomes/measures. These associations were strongly dependent upon the male sex of the fetus but independent of fetal genotype for AS3MT.

In this large-scale, Han Chinese population-based genetic association study for genetic susceptibility to schizophrenia of a three-gene cluster region, AS3MT-CNNM2-NT5C2, two SNPs with independent effects, rs11191419 and rs11191514, were identified. Rs11191419 is located on the 5' (potential promoter) region of AS3MT, while rs11191514 is located in one of the introns of CNNM2.

The combined analysis confirmed evidence of genome-wide significant associations in the Han Chinese population for three loci, at 2p16.1 (rs1051061, in an exon of VRK2, P=1.14 x 10-12, odds ratio (OR)=1.17), 6p22.1 (rs115070292 in an intron of GABBR1, P=4.96 x 10-10, OR=0.77) and 10q24.32 (rs10883795 in an intron of AS3MT, P=7.94 x 10-10, OR=0.87; rs10883765 at an intron of ARL3, P=3.06 x 10-9, OR=0.87).

The present study found that rs3740400 in As3MT and rs156697 in GSTO2 were strongly associated with the arsenic species (%iAs, %MMA and MMA/iAs and DMA/MMA ratios) in urine of the occupationally exposed workers and they may influence methylation capacity.

Data, including date from studies in knockout mice, suggest that As3mt is involved in energy metabolism in a sex-specific manner, independent of inorganic arsenic poisoning; thus, As3mt may be involved in cellular processes beyond methylation of inorganic arsenic.
